White: "It has a symbiotic relationship with otherworldly spirits. They aid it while hunting in exchange for fresh life energy from its victims."
This currently stands as the best 'Dex entry, in my opinion. Not as keen on the Black because it's a direct reference to Necturna's interaction with humans, which definitely makes sense (as it comes from a human-compiled PokeDex) but draws away from some of the plant-spirit vibe given off in the White entry.
Black: A Necturna was once seen draining life from a young willow until it dried up to make a dead bramble flourish again.
This, while perhaps not the best flavor-wise, is an interesting concept and kind of makes me wish that the spectral boundary between life and death concerning Ghost-types, but Necturna especially given its plant-nature, was more embellished.
Going to toss my hat into the ring, if only to perhaps inspire someone else? At the moment this remains a rough draft.
Necturna, the
Wilting Pokemon.
White: Necturna shadows the trees of dense forests. Its vine is a fierce weapon, though Necturna only strikes when it senses danger.
Black: A spectral form of the woes of the forest, Necturna protects the surrounding nature from further harm.
Justification (Species Name): I like the idea of "Wilting" over "Wilted" as the latter seems a bit
too dead for my tastes. Wilting implies that it is decrepit, but not fully run-down and can still guard its shrine successfully. I also much prefer singular species names to those that span two words, but again that's personal taste.
Justification (White): Attempted to convey the Forewarn ability a bit in this one while retaining the Grass/Ghost imagery. Concerned that "shadows" implies more of a Dark-type nature than that of a Ghost-type.
Justification (Black): More of a try on the "maiden" aspect of Necturna here. Not gonna lie, this may have been inspired by the movie marathon I had this weekend (Spirited Away / Nausicaa of the Valley of the Wind) and the fact that my little sister is pumped for the new Lorax movie...
